Flexible electrodes with excellent electrochemical properties have been the hot research subject in order for fabrication of flexible energy storage devices that are required in our mordern society. Nevertheless, conventional flexible carbon-based materials are unsuitable for daily use due to their low capacitance limitations. To address this challenge, we have developed a spinel-structured NiCo2−xFexO4 (NCFO) electrode material and self-assembled it on rGO to create a flexible electrode material of NCFO@rGO, which exhibits the multi-metal synergistic effect, reduced electron transfer distance and enhanced transfer rate, thereby enhanced energy storage capacity. The NCFO@rGO electrode successfully addresses the demands of flexible energy storage devices by providing both flexibility and high specific capacitance. We performed electrochemical correlation performance tests at current densities of 1, 2, 5, 10, 20, 40, and 60 A g−1, respectively. The electrode exhibits a specific capacitance of 2350 F g−1 at 1 A g−1, with a capacitance retention rate of 85.4 % after 10,000 cycles, indicating excellent electrochemical performance and stability. The NFCOrGO//rGO device demonstrates an impressive energy density of 49.73 Wh kg−1 at a power density of 1233.44 W kg−1.

State of health (SOH) is one of the most important indicators for the lithium-ion batteries' security, reliability and failure, therefore SOH estimation attracts close attention spontaneously. In this paper, a two-layer full data-driven SOH estimation model based on hybrid algorithm composed of multi-kernel relevance vector machine and extreme learning machine optimized with ant-lion optimization (ALO-MKRVM-ELM) is presented. In the model, a pre-estimation layer and an error compensation layer are assembled organically, which use MKRVM algorithm and ELM algorithm respectively. Meanwhile, to solve the problem of tedious debugging for parameters in MKRVM and ELM, ALO algorithm is introduced properly. In addition, considering both of estimation accuracy and calculation complexity, the feature factors for SOH estimation, which can be extracted from the battery's practical operation process, are elaborately selected through correlation analysis also. Finally, the performance comparison against various estimation models was carried out by using two groups of aging experiment datasets from Center for Advanced Life Cycle Engineering (CACLE) and Intelligent Power Laboratory (iPower-Lab) at our university, where CS2-type and ternary lithium-ion batteries were tested respectively, and three statistical evaluation indexes, i.e., the MAE, RMSE, and R2, are applied to assess the estimation results numerically. The experimental results indicate that both accuracy and robustness of the proposed model have been improved significantly.

The escalating global energy demand, coupled with the urgent need to combat climate change, underscores the necessity for effective and sustainable energy storage solutions. Phase change materials (PCMs) have emerged as a viable technology for thermal energy storage, particularly in solar energy applications, due to their ability to efficiently store and release thermal energy during phase transitions while maintaining a near-constant temperature. This paper addresses the limitations of traditional thermal energy storage systems and explores the advancements in PCM integration within various solar energy systems. We discuss innovative methods to enhance heat transfer rates and thermal conductivity, including modifications of extended surfaces, heat pipes, cascading PCMs, encapsulation techniques, and the incorporation of nanoparticles. These enhancements can improve system performance by up to 73 %, with nanoparticle dispersion identified as the most economically viable solution. Additionally, we provide a comprehensive overview of the implementation of the artificial intelligence approach in optimizing PCM-based thermal energy storage systems, emphasizing the effectiveness of ensemble learning frameworks for accurate modeling. The review also highlights the development of nano-PCMs, which demonstrate significant improvements—25.6 % in charging and 23.9 % in discharging rates—compared to conventional PCMs. Furthermore, we analyze the economic and environmental implications of PCM-based systems, focusing on critical issues such as carbon emissions, waste minimization, biodegradability, and alignment with circular economy principles. Finally, we discuss the major challenges and future research directions necessary for advancing PCM-based thermal energy storage systems. It is hoped that this article will update readers and experts working in this area on the recent advancements in PCM-based TES systems and provide an in-depth understanding of ML potentials in revolutionizing PCM-based solar energy storage systems.

Vanadium-based oxides have gained significant attention as promising cathode materials for aqueous zinc-ion batteries, owing to their high theoretical capacities, the ability to undergo multi-electron transfer, and varied crystal structures. Despite these advantages, challenges related to structural instability and poor electrical conductivity remain significant barriers to their practical application. In this study, Cr-doped VO2(B) nanorods were prepared using a hydrothermal treatment process as a promising candidate for aqueous zinc-ion battery cathodes. The multivalent nature of vanadium promotes a variety of redox reactions, resulting in high specific capacities. Chromium ion doping increases oxygen vacancy defects and provides efficient channels for electron transfer. The nanorod morphology offers an increased specific surface area, thereby promoting a higher density of active sites. Positron annihilation lifetime spectroscopy indicates that the generated defects exist in the form of single vacancies. Thanks to the unique tunnel structure and micro-morphology advantages, the CrVO cathode exhibits rapid electron transfer and superior reaction kinetics. Electrochemical performance is optimized at a chromium ion doping concentration of 6 at.%, achieving a high specific capacity of 312.8 mAh g−1 at 0.1 A g−1 and retaining 188.3 mAh g−1 at 5 A g−1 after 2000 cycles, with a remarkable capacity retention of 90.39 %, indicating exceptional long-term cycling stability. This work optimizes the electrochemical performance by introducing different concentrations of chromium ions into the monoclinic VO2, thereby altering the Cr3+/Cr6+ and V4+/V5+ ratio, providing a feasible approach for developing high-performance vanadium-based aqueous zinc-ion battery cathodes.

In this study, 1-octadecanol/1-dodecanol eutectic phase change material was impregnated into beech wood and pine sapwood using vacuum and pressure impregnation methods to enhance thermal energy storage capacity. The weight percent gain was found to be 55.2 % for beech and 96 % for pine sapwood. Digital microscopy and density distribution analyses revealed that the phase change material was primarily concentrated in the vessels of beech and the earlywood tracheids of pine sapwood, with a uniform distribution. The porosity of the wood was critical to the impregnation efficiency of the phase change material. Fourier transform infrared spectroscopy confirmed the physical bonding mechanism between the phase change material and wood. Differential scanning calorimetry demonstrated that the pore structure of the wood enabled the phase change behavior of the phase change material, leading to higher efficiency in the storage of thermal energy. The melting and freezing latent heats of impregnated beech were 84.8 J g−1 and 84.7 J g−1, respectively, while those of pine sapwood reached as high as 111.9 J g−1 and 111.8 J g−1, indicating a significant heat storage capacity. Thermogravimetric analysis revealed that the thermal stability of impregnated wood decreased due to the phase change material evaporation at high temperatures. Additionally, the thermal conductivity of beech and pine sapwood increased by 58 % and 50 %, respectively, after the phase change material impregnation, while their specific heat capacities increased by 167 % and 217 %, respectively, compared to untreated wood. Finally, leakage experiments confirmed that applying a coating substantially reduced the phase change material leakage, although some residual leakage remained, requiring further treatment. These findings provide valuable insights that may contribute to the application of the phase change material-impregnated wood for thermal energy storage in construction.

Thermal performance enhancement of latent energy storages and phase change material (PCM) based thermal control devices has been a challenging endeavor owing to the limitations imposed by material properties, confinement geometry, thermal convection physics, and poor thermal performance towards the end phase of the melting. Present study focuses on the melt front evolution and resulting thermal performance comparison of a two-dimensional square cavity latent energy storage with different sequential arrangements of cold and hot bounding surfaces. Here, each lateral surface is divided into two sections, designating them as hot surfaces and cold surfaces, a total of 216 different sequential arrangements have been examined. The novelty of the present investigation is that the thermal performance of all the possible positions of four thermally active walls in a latent heat storage system, undergoing simultaneous charging and discharging, have been critically examined. Boundary temperature, total area of the hot surface, cold surface, and the adiabatic wall are kept identical. Numerical simulations are performed with an enthalpy porosity technique based finite element solver. A clear elucidation of the melt dynamics is presented by tracking the unsteady melt front, portraying liquid fraction profiles, and estimating boundary heat transfer. The investigation revealed that the test cases with hot and cold surfaces placed alternatively on the lower half of the square cavity yielded higher heat accumulation. Moreover, when the cold surfaces were placed at the horizontal top wall with hot surfaces positioned at the right bottom and left bottom of the square cavity, the system exhibited superior melt fraction development during the final phases of melting. Buoyancy driven Rayleigh Benard convection current favouring the generation of higher thermal gradient at the heat transferring surfaces is observed for the aforementioned typical sequential arrangements of cold and hot bounding surfaces. These promising results are having potential applications in the design and development of high-performance systems involving simultaneous latent energy storage and recovery processes such as renewable energy storages, electronic cooling packages employing phase change materials, etc.

Sodium-ion batteries (SIBs) are undergoing a significant resurgence to either complement or substitute the costly lithium-ion batteries (LIBs) in electrical energy storage systems and other applications. However, the development of SIBs is hindered by issues such as low energy density, short cycle life, and the large ionic radius of sodium. Therefore, developing high performance cathode materials is crucial for enhancing the overall performance of SIBs. Among various cathode materials, layered transition metal oxides (LTMO) have attracted significant attention due to their advantages, including low cost, simple preparation process, and dense structure. Nevertheless, LTMO materials face challenges such as complex phase transitions, sluggish ion transport kinetics, and interface issues between the electrode and electrolyte during charge and discharge process, making their modification necessary. This paper reviews recent advances in the modification strategies of LTMO materials such as doping, morphology control, and surface coating. It also discusses future development directions, aiming to accelerate the application of LTMO in SIBs and promote their early commercialization.

The battery case is the core part of a lithium battery, the quality requirements are extremely high, and its size measurement is easily affected by personal factors, resulting in human-controlled errors. A method based on the improved Canny operator is proposed to aim at the problems of low efficiency and high cost in the dimension measurement of the bottom and top of the battery case. Firstly, the image acquisition system is designed to complete the construction of the hardware platform, the camera calibration is achieved in Halcon, RGB processes the image to greyscale and grey value enhancement is used to increase the image contrast, and the improved bilateral filter denoising performs the edge detection, the threshold segmentation and the improved Canny operator to achieve the sub-pixel level size measurement and ensure the accuracy of the edge positioning. Comparison experiments show that the absolute error of the top and bottom diameters of the battery case measured by the algorithm in this paper is less than 0.007 mm, the relative error is less than 0.06 %, and the average error is within 0.0068 mm and 0.0064 mm, respectively. The measurement speed is only about 200 ms, which is much faster than that of the manual measurement of more than 7 s, and it meets the requirements of industrial applications.

Zinc-air batteries have emerged as a key research focus in the new energy sector in recent years, owing to their high energy density, enhanced safety, and low-carbon environmental protection characteristics. But its limited output power and lower charging and discharging stability have hindered its commercialization applications. In this work, N, S co-doped lignin-based hierarchical porous carbon nanocages loaded with binary metal sulfides (FexNiSy-TLCs-T) were fabricated firstly using lignin as a carbon source and then using nano-MgO as templates. Meanwhile, lignin was modified by amination via Mannich reaction, and then ligand compounds were formed with metal ions to prepare nano-restricted domain catalysts. The prepared FexNiSy-TLCs-T not only exhibit bifunctional catalytic activity for oxygen reduction reaction and oxygen evolution reaction (ORR/OER), but also demonstrate a half-wave potential (0.84 V) and overpotential (270 mV) comparable to those of commercial noble metal catalysts. Furthermore, FexNiSy-TLCs-T also exhibited superior methanol toxicity resistance and stability compared to commercial Pt/C catalysts. This work presents a green and economical approach to construction Zn-air batteries air cathode electrocatalyst, highlighting the potential of biomass-based carbon materials for green energy conversion and offering innovative pathways for high-value lignin utilization.
